FDA grants RMAT Designation for OBX-115 for the Treatment of Advanced Melanoma

“RMAT designation for OBX-115 highlights the unmet need in ICI-resistant melanoma and OBX-115’s potential to provide patient-centric, transformative care in this setting,” said Parameswaran Hari, M.D., Chief Development Officer of Obsidian. “In an oral presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, initial Phase 1 data showed that OBX-115 exhibited a favorable safety profile relative to what has been observed historically from IL2-dependent non-engineered TIL cell therapy, encouraging efficacy in patients with heavily pre-treated disease, and compatibility with non-surgical core needle biopsy tumor tissue procurement. We look forward to continued collaborative interaction with the FDA as we advance OBX-115 clinical development in both melanoma and non-small cell lung cancer (NSCLC).”
